Answer:

the second one is a better deal.

Step-by-step explanation:

<em>first deal:</em>

6 rolls for 9.24

9.24/6 = 1.54

1.54$ per roll

<em>second deal:</em>

18 rolls for 27.54

27.54/18 = 1.53

1.53$ per roll

the second one is one cent cheaper

Total freshman = 58. Number of freshman who prefer cheese toppings= 14. Determined the probability that a freshman prefer cheese
Yakvenalex [24]

Answer:

The probability that a freshman prefer cheese toppings  is   0.241

Step-by-step explanation:

Probability of any event E =  \frac{\textrm{Number of favorable outcomes}}{\textrm{Total number of outcomes}}

Here, let E   :  Event of choosing cheese toppings

So, the number of favorable outcomes = 14

Total number of outcomes = 58

So, P(E) =  \frac{\textrm{Number of students who like cheese toppings}}{\textrm{Total number of students}}

or, P(E) = \frac{14}{58} = 0.241379

So,the probability that a freshman prefer cheese toppings  is   0.241379

Rounding of 0.241379  to the <u>nearest thousandth</u>, we get

Here , in 0.241379 thousandth digit is 3, and 3 < 5,

so the value of P(E) = 0.241

Is there a way to quickly find a function if you have a handful of ordered pairs?
Scilla [17]
Yeah. You basically have to look at every x value and see if for every x value, is there ONLY one y-value. So in your example, it is a function because every x value has only one y value. Let’s say you had (1,3) and (1,5). That would not be a function because the x value of 1 has TWO y values (3 and 5), therefore it is not a function.

That’s how you can easily spot if something is a function by just looking at a handful of ordered pairs. I hope this makes sense.

Two mechanics worked on a car. The first mechanic worked for 10 hours, and the second mechanic worked for 5 hours. Together they
Anvisha [2.4K]
You would first make an equation to show their individual price per hour multiplied by hours worked then added together to equal total cost. let X be mechanic 1 and Y be mechanic 2

10x + 5y = 1225

the second equation will use their price per hour added together to equal combined cost per hour

x + y = 180

you would solve by substitution. to do so, isolate either x or y in the second equation. for convenience, I will isolate x

x = 180 - y

plug in (180 - y) for x in the first equation

10(180-y) + 5y = 1225

1800 - 10y + 5y = 1225

-5y = -578

y = 115.6

this means that the second mechanic charges $115.60 per hour

to find the price per hour for the first mechanic, plug in (115.6) for y in the second equation

x + 115.6 = 180
x = 64.4

the first mechanic charges $64.40 an hour
